Soil microplastics pollution in agriculture

Microplastics in Agricultural Soils

AI summary · Read the abstract

Researchers reviewed what is known about microplastic contamination in agricultural soils, noting that despite hundreds of millions of tonnes of plastic entering the environment annually, very little is understood about how microplastics persist, migrate, and affect soil ecosystems. This knowledge gap is concerning given that contaminated soil directly affects food crops consumed by humans.

Microplastics in Soil: An Emerging Threat

AI summary · Read the abstract

Researchers reviewed the emerging problem of microplastic pollution in soil, tracing contamination to agricultural practices, industrial activities, and atmospheric deposition, and examining downstream risks to ecosystem health and human well-being.

Impact of Microplastic Pollution on Soil Health

AI summary · Read the abstract

Researchers review how microplastics enter agricultural soils from plastic mulch films, sewage sludge, and irrigation water, documenting their effects on soil microbial communities, nutrient cycling, and overall soil health in ways that may threaten long-term agricultural productivity.

Current Situation and Ecological Effects of Microplastic Pollution in Soil

AI summary · Read the abstract

Researchers synthesized existing knowledge on microplastic contamination in soils, finding that particles accumulate widely, disrupt soil ecosystems, and can enter food crops — yet soil remains far less studied than water environments. Closing this research gap is urgent because soil health underpins food production and microplastics in agricultural land could reach human diets.
